8423528 divided by 717 
The aim is to understand the frequency of 717 in 8423528.

Advancing to step 1:
717 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 717

Moving on to step 2:
84 divided by 717 is 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 717

Moving on to step 3:
717 goes into 842 1 times with a remainder of 125.
The next digit of our result is 1. 
Result so far: 1.0
If we take 717 away from 842, we end up with 125.
Fetch the next digit (3) from the dividend, attach it to 125 and continue: 1253 / 717

Going ahead to step 4:
When dividing 1253 by 717, we get 1 with a remainder of 536.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 717 from 1253, we get 536.
Append the next digit (5) from the dividend to 536 and continue with: 5365 / 717

Moving on to step 5:
If we divide 5365 by 717, we get 7 and a remainder of 346.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we subtract 5019 from 5365, we get 346.
Grab the next digit (2) from the dividend, add it to 346, then carry on: 3462 / 717

Step 6:
717 goes into 3462 4 times with a remainder of 594.
Put 4 as the next digit of the answer. 
Result so far: 1174.0
If we subtract 2868 from 3462, we get 594.
Bring next digit (8) of the dividend behind the 594 and repeat the process: 5948 / 717

Going ahead to step 7:
When dividing 5948 by 717, we get 8 with a remainder of 212.
The number 8 becomes the next digit in our result. 
Result so far: 11748.0
Subtract 5736 from 5948 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 8:
717 can be fit into 2120 2 times, resulting in a remainder of 686.
Put 2 as the next digit of the answer. 
Result so far: 11748.2
The remainder is 686 after subtracting 1434 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Moving on to step 9:
6860 divided by 717 is 9 with a remainder of 407.
Put 9 as the next digit of the answer. 
Result so far: 11748.29
If we take 6453 away from 6860, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Moving on to step 10:
When dividing 4070 by 717, we get 5 with a remainder of 485.
Record the quotient 5 as the next digit in the result. 
Result so far: 11748.295
If we subtract 3585 from 4070, we get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 11:
717 goes into 4850 6 times with a remainder of 548.
Put 6 as the next digit of the answer. 
Result so far: 11748.2956
Subtract 4302 from 4850 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Moving on to step 12:
If we divide 5480 by 717, we get 7 and a remainder of 461.
Write down 7 as next digit of the result. 
Result so far: 11748.29567
If we subtract 5019 from 5480, we get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Going ahead to step 13:
When dividing 4610 by 717, we get 6 with a remainder of 308.
Put 6 as the next digit of the answer. 
Result so far: 11748.295676
If we subtract 4302 from 4610, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 14:
When dividing 3080 by 717, we get 4 with a remainder of 212.
The number 4 becomes the next digit in our result. 
Result so far: 11748.2956764
Deduct 2868 from 3080 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 15:
If we divide 2120 by 717, we get 2 and a remainder of 686.
Use 2 as the next digit of our solution. 
Result so far: 11748.29567642
The remainder is 686 after subtracting 1434 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

The final outcome is 11748.29567642, with a leftover of 6.86e-07.
